PEN CLIP..

Application filled May 22, 1920. Seria1 No. 383,454. A' y 2'."

To all whom t may concern.'

Be it knownthat I, ROBERT G. PiLKiNG- ToN,'a citizen of the United States, residing at Chicago, in the county of Cook and State 5 of Illinois, have invented certain new and useful Improvementsin Pen Clips, of which the following is a specification.

My invention is a clip for fountain pens and has for its object the provision of an efficient and improved method of attaching a clip to a fountain pen and at the same time providing an ornamental end to the cap o-f the pen.

My invention may be best understood by reference to the accompanying drawings, of

which- Y i Fig. 1 is a perspective view of a fountain pen equipped with my improved clip, and

Fig. 2 is a view of the pen having the cap shown in section.

Referring to the figures, 10 is the barrel of a fountain pen of the ordinary construction provided with a screw thread 11, which serves to secure the cap 12, which is provided with the customary offset 13, adapted to be brought in contact with the end 14 of the casing 10, thereby sealing the pen against leakage when not in use.

The `cap 12, at its upper end, is provided with a. groove 15, anda slightly reduced portion 16. The metallic cap 17 is provided to fit over the reduced portion and have its ends 18 spun into the groove 15, thereby securing the metallic cap 17 firmly 35 to the pen cap 12. The 4cap 17 may be made ofany ornamental metal, such as gold or silver, or it may be made of brass and nickel plated. Soldered to the cap 16 is a clip 19, consisting of the customary spring shack 20, terminating in a pawl or roller 21.

Besides forming a point of attachment for the clip 19, the cap 17 also serves to secure a sealing washer 22, which serves to close the top of the cap 12. The washer 22 may be made of metal, rubber, or any suitable material.

Many advantages result from my improved construction, among which I may call attention to the fact that by using the construction herein shown, one is able to make the pen cap 12 out of rubber tubing, instead of a solid piece of rubber, the washer 22 providing an efficient seal for the top of the cap 12.

Another 'advantage of my invention) isv that the clip" 19 Vis mounted on the metal cap 17, thereby providing a joint whicliis 'capable of being hard soldered, and further that the cap 17 itself is mounted yon the end of the cap 12 and has a large bearing upon the rubber cap 12, thereby forminga secure fas-v tening.

Many variations may be made'from the precise structure herein disclosed without departing from the spirit ofV my invention,`

since I claim: .Y

1. In a writing instrument of the class described, in combination, a main cap hav ing both ends open, a sealing means extending across one of said open ends, a supplemental cap fitted over said last mentioned open end of the main cap with its sides in engagement with the sides of said main cap, said supplemental cap being secured to said main cap so as to press said'sealing means in close contact with the adj acentopen end of the main cap.

2. In an article of the class described, in`

combination a cap and clip, comprising a main cap having its rear end open, a circumferential groove cut therein, a washer, a supplemental metal cap adapted to tit over the rear end of the main cap, the open end of said supplemental cap being spun into the groove in the main-cap thus firmly pressy ing the washer to contact'with the open rear end of the main cap, causing an airtight pocket to be formed in the cap when the `pen section is in abutment relation with the loffset in the cap, and a clip affixed to said metal cap.

In an article of the class described, in combination a cap and clip comprising a cylindrically shaped hollow tube threaded internally near one end, a circumferential groove cut in the tube opposite the threaded end. a washer, a metal cap adapted to enclose the end of the tubing in which the groove is cut, the open end of said'cap being spun in said groove thereby eecting a tight -cap fitted over said last mentioned open end .ofthe mail; Cap with its sides. engagement.

100 relation between the washer and the tube,

With the sides of said main cap, said supplemental cap being secured to said main Cap so as to press said sealing means in close Contact With the adjacent open end of the main cap, and a clip attached to said supplement-a1 cap.

5. In a Writing instrument a main cap 0l cylindrical sha-pe open at both ends, a supplemental cap having elongated cylindrical sides snugly fitted throughout their length to the outer surface of said main cap and secured thereto and covering the adjacent open end thereof, sealing means between said supplemental cap and last mentioned open end of the main cap, and a clip secured to said supplemental cap.

6. In a fountain pen a barrel, a non-metallic main cap adapted to covel1 the Writing point when not in operation, a metallic supplemental cap having elongated cylindrical sides snugly fitted over one end of said main cap and secured thereto, and a metallic clip secured to said metallic supplemental cap and extending alongside said main cap with its Jfree end in engagement therewith.

In Witness whereof I have hereunto sulo,u scribed my name.
